Wax Salad Dressing had beginning work-in-process of $257,810 consisting of $101,440 of materials and $156,370 of conversion costs. There were 16,000 units (one unit equals one case of salad dressing) in beginning work in process 40% complete as to conversion costs. Materials are added at the beginning of the process. During November, 34,000 were transferred out; 1,000 were spoiled and 9,000 remained in ending inventory. The spoiled units were 60% complete for conversion cost.
